Tag Info

{two-column} is about the \twocolumn command and the class option of the same name. For questions about the {multicol} package, use the appropriate tag instead.

A lot of document classes, like `article`, `report` and `book`, provide for a two column layout using the class option `twocolumn`. There are also the commands `\twocolumn` and `\onecolumn` that can be used to switch to a two- or single-column layout within a document.

The dimensions `\columnsep` and `\columnseprule` can be modified to set the space between the columns and the width of the rule separating the columns.

In a two-column layout, the floating environments `table*` and `figure*`, being alternate versions of the environments `table` and `figure`, spread over both columns.
